  • Empirical evidence ftw.

  • hoefia, what about the saddle angle?

    fairly certain it's fine. it's comfortable and I don't slide around.
    will try moving saddle back a bit and see how I get on the next few days.

    the singlespeed just feels so much smoother and easy as well as comfy. well, not strange at all, I guess it's down to so much better efficiency in the drivetrain. but I'll need those gears.

  • Same contact points on both?

    (Saddle/bars/pedals/tape/levers)

  • Setting up from a bike that fits according to Scherrit start with saddle height, adjust if different crank length, then saddle noose behind bb same as bike that fits and same for saddle noose to bar reach. Cleats should always be in the fitted position. Always worked for me.

  • ^coming from the man who rode on a completely bent and fucked up saddle who complained his fit was incorrect!

  • For the new bike with 10cm more saddle to bar drop which I really like and does not give me the back ache I dreaded this leaves me in a position where my knees get very close to the bars when climbing out of the saddle. Anybody else had this?

  • Same contact points on both?

    (Saddle/bars/pedals/tape/levers)

    none of the above...

  • May just be unfamiliarity - ride the road bike as much as possible for the next few days.

    I have the same shape bars on all my bikes, and usually use an Arione saddle- so I'm familiar with what I hold and what I sit on from bike to bike.

  • likewise, same contact points on all my bikes

  • dopest ghost, do you mostly ride on the tops rather than the extensions?

    Have you tried just looking ahead with your eyes, rather than your whole head?

    Also, have you tried stretching?

    Nah I mostly ride on the extensions. I'm not sure what you mean about looking ahead with my eyes though?

    I did 115 miles yesterday and although I was sore I was a lot less sore than usual so I think I will go for a setback seat post.

  • Pretty sure you already got a layback!!

    Maybe a longer stem?

    When I asked about your stretching though I was serious.

    Also, carrying any kind of bag over any distance won't be doing you any favours.

    Get some bottle cages on there and a hip pouch innit!

  • I'm trying to match up my fit from my TCR to my Condor.

    Is the best way going to be with real tape measures and spirit levels, or is there a way I can just do it now with maths?

    The geos are fairly similar, but the TT and seat angle are both shorter on the TCR. Any helpful online programmes?

    Cheers.

  • Why complicate it with maths instead of just getting a tape measure out?

  • ^^ slow day at work.

    Neither bike or a tape measure in the office.

    Yeah I'm 100% sure that the bag is the cause of the back pain. It hurts exactly where the bag sits on my back. I noticed that on yesterdays ride.

    In this pic ths saddle is as far back as it will go on the rails, I'm not sure its even safe to be clamped where it is.

    I was thinking of getting one of these : http://www.wiggle.co.uk/thomson-elite-setback-seat-post/?lang=en&curr=GBP&dest=1&utm_source=pla&utm_medium=base&utm_campaign=uk&kpid=5360417450

    and also a longer stem if that didnt solve the issue.

    As for stretching, I do stretch but not as often as I should. I forget quite a lot. I am going to be joining a Yoga for sports class next week though which will help I imagine

  • outside back of left knee has really cramped up today
    I feel stooopid :(
    (might move saddle down before I go home)

  • hoefla, get stretching!

    Dennis, ^ may be of use to you as well. The stretches are clearly detailed and should help with flexibility.

  • wow that looks pretty good.
    I had a read of http://www.stevehoggbikefitting.com/bikefit/2011/11/knee-pain/ as well.
    following niggles on saturday spent the evening and yesterday stretching as much as I knew how to, surprised it's so much worse today :/
    just don't want to mess my knee up.

    Cheers, I'll check it out.

    My knees are okay though.

  • so maybe a setback seatpost is in order rather than a longer stem?

    More set-back is not a solution in lieu of a longer stem. The more you push the saddle back the more you rotate yourself counter-clockwise around the bottom bracket, effectively lowering your stem.
    Why do people advocate KOPS? For the simple reason that foot length is highly correlated with the length of the antebrachium (lower arm). They should, in general, be nearly identical in length. The foot is rarely longer--- and when shorter its generally as a result of wearing ill-fitting shoework during growth.
    Height and foot length too is also more or less linked. The variations are more less in leg segment length, resp. torso, neck. head and brachium (upper arm) length. That is why one can more or less suggest a stem length on the basis of frame size.

  • ^ wot?!

  • If you look at the history of the letter 'z', it was previously know as 'izzard' among other things; therefore EdwardZ is Eddie Izzard AICM£5.

    I quite like this new bicycle routine he's working on.

  • ^ wot?!

    The most famous observation was that the length of a person's "arm span" (tips of the middle fingers to tips) is more or less the same as their height.

    Measure the length of your foot. Now measure the length of your lower arm: elbow to wrist. Compare the lengths!

    So we see that arm length is correlated to height, Foot length is correlated to lower arm length.

    Variations are in upper-arm length, neck, shoulders.. hip width.. But they are themselves correlated with other limb segment lengths...

    How about.. Length of hand... length of face?

    The correlation of height to shoe size can't clearly be as strong but its reasonable.. its good enough that height can be predicated from shoe size..

    Measure the length of your tibia (shinbone). Now measure the width of your hips. Compare!

    Cultural or racial differences are, however, found in femur length. There is no good correlation between other limb segment lengths and femur lengths that cuts accross groups. The differences in the ratio of femur to tibia lengths are, however, under 30% accross 95% of the population.

    Race? Blacks have a greater tendency toward mesomorphy and, on average, have shorter trunks and longer extremities than whites. Since black youths tend to have also more narrow hips than white youths of the same stature its follows that blacks tend to have longer relative femurs. The reason, however, that blacks tend not to dominate in cycling-- in contrast to track and field where the vast majority of the record holders in the men's 100-meter dash have been black athletes--- is that they also tend to have more mass and more fat distribution in their extremities--- counterproducture to elite cycling performance.

    Oh.. before I forget.. No women don't have longer legs then men. The association is a cultural norm derived from the observation that girls and boys have different growth patterns and during male puberty the same aged girls have comparatively longer legs than the boys. Long legs = fertile. The reality of the matter.. Take away the high heels and..

    Sample size of 2 but it's not looking good so far.
